Good night...

I started a couple of days learning java (and processing). I've bumped into a problem that's driving me nutts. Here it comes:

float points[][];
String roughpt[] = loadStrings ("points.txt");
for (int i=0; i<roughpt.length; i++) {
 float bin[] = float(split(roughpt[i]));
 points[i][0] = bin[1];
 points[i][1] = bin[2];
 points[i][2] = bin[3];
}

And the log says something like this "The variable "points" may be accessed here before having been definitely assigned a value.", pointing line 5.
Does someone now where's my mistake?

Thanks a lot.

this error means just what it says: "The variable "points" may be accessed here before having been definitely assigned a value."

which is just that the compiler is concerned that it sees points[] in use, but there's a possibility that the code that uses points[] (inside your loop) might happen before points[] has been set to anything.

you can make the error go away by changing:
float points[][];
to
float points[][] = null;

which just tells the compiler that you know what you're doing and will assign it to something later. in your case it's a little silly, but in others, it can sometimes help prevent dumb mistakes.

float points[][] and float[][] points are identical, it's just a matter of preference. there are some minor cases where it makes a difference (float[][] pieces1, pieces2 might give you a headache) but it's generally identical.
